The nurse is caring for a client who is being discharged following coronary artery bypass graft surgery. Discharge instructions would include:

Resume smoking initially to help manage stress and anxiety.

Consume a high-fat diet to promote weight gain and energy.

Avoid physical activity and rest as much as possible.

Continue taking all prescribed medications as directed.

"Can you rate your pain on a 0-10 scale?"

Answer and Explanation

The Correct Answer is D

A. Resume smoking initially to help manage stress and anxiety:
Smoking is a significant risk factor for cardiovascular disease and can worsen the prognosis after coronary artery bypass graft (CABG) surgery. Smoking increases the risk of coronary artery disease and impairs healing after surgery. Therefore, advising the client to resume smoking, even temporarily, is unsafe and completely contrary to health recommendations for post-CABG care. Smoking cessation should be emphasized as a key part of the recovery process.

B. Consume a high-fat diet to promote weight gain and energy:
A high-fat diet is not recommended for individuals with coronary artery disease, especially after CABG surgery. Consuming a diet high in saturated fats and cholesterol can lead to further plaque buildup in the coronary arteries, increasing the risk of atherosclerosis and cardiac events. After CABG, patients are typically encouraged to follow a heart-healthy diet that is low in saturated fat, high in fiber, and rich in fruits, vegetables, and lean proteins to support overall heart health and recovery.

C. Avoid physical activity and rest as much as possible:
While rest is essential immediately following surgery, complete avoidance of physical activity is not advisable long-term. In fact, early and gradual physical activity is a key component of rehabilitation after CABG surgery. A sedentary lifestyle can increase the risk of complications such as blood clots, muscle weakness, and weight gain, while physical activity helps improve circulation, heart function, and overall recovery. The nurse should encourage the client to gradually resume physical activity according to the guidance of their healthcare provider, often starting with light walking and progressing as tolerated.

D. Continue taking all prescribed medications as directed: Following coronary artery bypass graft (CABG) surgery, it is essential for the client to continue taking all prescribed medications, including antiplatelets, statins, beta-blockers, and any other medications ordered by the healthcare provider. These medications play a critical role in preventing blood clots, controlling blood pressure, reducing cholesterol levels, and preventing future cardiac events. Stopping or altering medications without consulting a healthcare provider could increase the risk of complications or recurrent cardiac events.

Correct Answer is C

Explanation

A. Hyperglycemia:
Although hyperglycemia can occur as a result of stress or corticosteroid use during the treatment of GBS (such as in the case of plasma exchange or IV immunoglobulin (IVIG) therapy), it is not the primary complication associated with GBS. While hyperglycemia requires monitoring and management, respiratory failure is a more immediate and critical concern.

B. Urinary retention:
Urinary retention can occur in some clients with neurologic disorders like GBS, but it is not as life-threatening as respiratory failure. The autonomic nervous system, which controls bladder function, may be affected, but urinary retention is usually manageable with intermittent catheterization or other interventions. It does not carry the same immediate risks to life or organ function as respiratory failure.

C. Respiratory failure:
In Guillain-Barré syndrome (GBS), the immune system attacks the peripheral nervous system, which can lead to progressive muscle weakness and paralysis. The most significant and potentially life-threatening complication of GBS is respiratory failure. This occurs because the paralysis can affect the muscles involved in breathing, including the diaphragm and intercostal muscles, leading to impaired ventilation. As the weakness progresses, the client may become unable to maintain effective breathing, requiring mechanical ventilation. Monitoring for signs of respiratory distress (e.g., increasing work of breathing, tachypnea, decreased breath sounds, or a drop in oxygen saturation) is critical in GBS, especially during the acute phase of the disease.

D. Hypertension:
Hypertension may be seen in some cases of GBS, particularly during the early stages of the disease, due to the autonomic dysfunction that can result from nerve involvement. However, hypotension (low blood pressure) is more commonly associated with the autonomic dysfunction in GBS rather than hypertension. Regardless, respiratory failure remains the most urgent complication to monitor for in clients with GBS.

A. Assess for conjunctival bleeding B. Encourage the use of sunglasses when outside C. Alternate the use of an eye patch on each eye D. Apply cool compresses for pain relief E. This result is consistent with partially compensated respiratory alkalosis. In respiratory alkalosis, the pH would be elevated (alkalotic), PaCO2 would be low (indicating hyperventilation), and the kidneys would attempt to compensate by lowering bicarbonate (HCO3). In this case, the low PaCO2 (23 mmHg) and the low HCO3 (14 mEq/L) demonstrate partial compensation. The pH is also elevated at 7.64, which aligns with alkalosis. This is the correct answer for partially compensated respiratory alkalosis.

Correct Answer is C

Explanation

A) Assess for conjunctival bleeding
Conjunctival bleeding refers to blood in the white part of the eye (the conjunctiva), which is typically associated with trauma, infections, or certain blood disorders, but it is not a common cause of diplopia (double vision). Diplopia in multiple sclerosis (MS) is more often due to nerve damage affecting the eye muscles or the pathways controlling eye movement. Therefore, assessing for conjunctival bleeding is not a priority intervention for a client with diplopia related to MS.

B) Encourage the use of sunglasses when outside
While wearing sunglasses may help alleviate light sensitivity, which is a common symptom in individuals with MS, it is not the most appropriate intervention for treating diplopia itself. Diplopia is typically caused by issues with eye muscle control or coordination, often related to the central nervous system. Therefore, while sunglasses might provide comfort, they do not address the underlying cause of the double vision.

C) Alternate the use of an eye patch on each eye
Alternating the use of an eye patch on each eye is an effective intervention for managing diplopia, especially when the cause is related to misalignment or weakness of the eye muscles. The eye patch works by covering one eye at a time to prevent double vision. In MS, this technique can help reduce the visual disturbance and provide relief until further interventions (such as eye exercises or medications) can be considered. This approach is commonly used to manage diplopia caused by nerve involvement affecting ocular muscle function.

D) Apply cool compresses for pain relief
Cool compresses may provide relief for eye irritation or inflammation, but they are not typically used to treat diplopia. Diplopia in MS is more related to neuromuscular dysfunction or nerve damage, rather than acute inflammation or irritation of the eye. Therefore, while a cool compress may offer temporary relief for other symptoms, it is not a targeted solution for double vision in this context.
